LIGHTING-FIXTURE.

Specification of Letters Patent.

Application filed July 3, 1912. series No. 707,404.

' of which the following is a specification.

This invention relates to lighting fixtures, the object of the invention being to provide a semi-indirect lighting fixture simple in I construction, practical in use, and in which 5 the parts are so constructed and organized that the several parts making up the fixture are readily detachable to permit easy access to the interior of the globe and in which also the globe will be so supported that danger of breakage thereof by reason of the expansion from the heat is avoided, and in which also the globe is rendered dust proof. 7

In the drawings accompanying and form ing partof this specification, Figure 1 1s a partly sectional View illustrating the present improvement; and Fig. 2 is a view taken inline 22, Fig. 1, looking downward.

, corresponding parts in the figures of the drawings. In the present improvement the fixture comprises a tube or hollow rod 2 supported in any suitable manner, as from the ceiling,

an having the usual canopy 3. Carried by i this zrpd, at its lower end, is a threaded memopenings for the reception of threaded fas-' toning screws for securing the globe in position. "The globe in the present instance, which may be made of any desired character of glass, but preferably opaque, is shown hemispherical, having an-- opening 10 at its underside for the passage of the stem or tube by means of 'which the glpbe is suspended or supported. In the present instance the apex; of the globe is formed with a bent collar 11 adapted to fit within the flange of the supporting pup 6. The upper edge of th'e'globe is provfded with an offset or ribl'wtl'i thereby forming'a circular rabbctodfiangcd edge for the reception ofa flanged metal ring 14 Similar characters of reference indicate,

adapted to fit and rest" therein. This ring is supported by any desired number of arms or rods 15, the inner ,ends of'which are carried by a collar 16 fitting'the tube 2 and secured thereto by' suitable set screws. This rin which in the present instance comprises two semicircular pieces of glass 18 recessed adjacent to thetube or stem 2 to fit around the same and maintained in engagement therewith by means of one or more springs 19 for each semicircular glass piece, these springs being located between the outer edges of the glass and the flanged end 20 of the metal ring.

Supported at the lower end of the stem 9-- 1s a cone-shaped member or canopy 21 for carrying the lamp sockets, and within this canopy the usual hickey, not shown, is located. The lower edge of this cone-shaped memberor canopy 21 is spaced above the inner walls of the globe so that when the globe is supported in position'by its supporting cup the globe cannot bind against this inner canopv, so that provision is made for the expansion of the glass and thus eliminating chances of breakage.

From the foregoing it will be observed that byremoving the supporting cup the globe may be readily removed from the fixture without interfering with or affecting the, position of the glass cover or of the supporting means therefor, so that the electric light fixtures are readily accessible by the removal of simply the dome or globe for repair or inspection of such fixtures, without taking down-the entire fixture or removing anything butthe globe and its supporting cup. Furthermore, it will also be observed that if it is desired to have'access to the dome or globe this can be readily obtained without even removing it, by simply removing the glass cover or either part thereof, and furthermore, that' this glass cover completely closes the dome or globe in such a manner that the same is dust proof, so that the necessity of cleaning the interior of the lobe-to remove particles of dirt and dust w icli freguently accumulatein open globes and denies and materially interferewith the light is thusv avoided.

In practlce the glass coverwill preferably be made of clear glass soas not to interfere with the passage ofthe light therethrough.

supports the multi-piece glass cover 17 -or the globe,

It will .alsobe observed that the glass-cover supporting ring is adjustable on the stem or tube 2 so as to bring it inproper position to fit within the recessed flange of the dome or globe as this may vary in manufacture. It will thus be observed that the globe or dome of semisplierical form is removable from the lower end of the stem quickly andis rigidly supported at the lower end of such stem when in position, without liability of its breaking by reason of expansion, and that such dome is dust proof by reason of the light is desired.

removable cover which is adjustably' carried .on the stem by a ring provided for this purpose, and which ring and the upper edge of the globe conform in shape one to the other,

the edge of the globe or dome being provided with a recessed flange for such ring, and that the removal of the dome can be efiected without interfering with the posi tion of the cover, and vice versai. The provision of the metal ring for holding the cover also tends to keep the globe true and preventsvibration and breakage thereof Without placing any strainthereon. This ring also, by reason of its location between the edge of the globe and the surface of the glass cover, serves to prevent breakage of one or the other when. assembled as well as preventing noise and rattle. In the present improvement it will also be observed that the dome 0r globe is so formed at its upper edge that the metal ring and the glass coverare entirely. concealed when the fixture is in posit-ion.

From the foregoing it will be observed that the present fixture provides what is known as a semi-indirect lighting fixture for hospitals and other places where a I claim as my invention: 1.
